QUESTION
I created an image and pushed to dockerHub, from an angular project. I can see that if I will go to localhost:80 it will open the portal. This are the steps:
...ANSWER
Answered 2021-Jun-14 at 15:35Your repository is private and requires login to pull image.
You need to create a registry credentials secret for kubernetes, as it do not uses docker credentials.
See https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
1. Create a secret named regcred:

I have an EKS node group with 2 nodes for compute workloads. I use a taint on these nodes and tolerations in the deployment. I have a deployment with 2 replicas I want these two pods to be spread on these two nodes like one pod on each node.
I tried using:
...ANSWER
Answered 2021-Jun-13 at 12:51You can use DeamonSet
instead of Deployment
. A DaemonSet
ensures that all (or some) Nodes
run a copy of a Pod
. As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected. Deleting a DaemonSet will clean up the Pods it created.
See documentation for Deamonset
QUESTION
I have master-slave (primary-standby) streaming replication set up on 2 physical nodes. Although the replication is working correctly and walsender and walreceiver both work fine, the files in the pg_wal
folder on the slave node are not getting removed. This is a problem I have been facing every time I try to bring the slave node back after a crash. Here are the details of the problem:
postgresql.conf on master and slave/standby node
...ANSWER
Answered 2021-Jun-14 at 15:00You didn't describe omitting pg_replslot during your rsync, as the docs recommend. If you didn't omit it, then now your replica has a replication slot which is a clone of the one on the master. But if nothing ever connects to that slot on the replica and advances the cutoff, then the WAL never gets released to recycling. To fix you just need to shutdown the replica, remove that directory, restart it, (and wait for the next restart point to finish).
Do they need to go to wal_archive folder on the disk just like they go to wal_archive folder on the master node?
No, that is optional not necessary. It is set by archive_mode = always
if you want it to happen.

The wordpress service is running confirmed by docker service ls
and the blog is up when visiting the blog url (which gets taken down after executing docker stack rm wordpress
).
Once wordpress is deployed using docker stack deploy
the stack looks like this:
ANSWER
Answered 2021-Jun-14 at 12:58You're using Docker Swarm
which can run over multiple nodes in cluster mode.
A plausible scenario is that traefik
is running on the node where you're executing the docker ps -a
command and the other containers are running on different node/s.
To confirm that there is more than one node you can try and execute docker node ls
. I can't think of any other scenario where you have a running service, but only one of the containers is visible (and you have a single host).
QUESTION
We have setup Redis with sentinel high availability using 3 nodes. Suppose fist node is master, when we reboot first node, failover happens and second node becomes master, until this point every thing is OK. But when fist node comes back it cannot sync with master and we saw that in its config no "masterauth" is set.
Here is the error log and Generated by CONFIG REWRITE config:

QUESTION
I am working on setting up a three node Docker swarm for a web application I support. Initially, we have Traefik setup as a reverse proxy. Traefik and the web app both run on the same web server and the web server is in a single node docker swarm. We are trying to add two additional nodes for application stability.
At the moment, I'm simply trying to understand Traefik load balancing along with Docker Swarm. I am deploying a Traefik v1.7 stack and including the whoami application. The docker-compose file for this first past looks like:
...ANSWER
Answered 2021-Jun-13 at 03:53Apparently Traefik can't drain the connections during update (maybe it doesn't have access to healthchecks and swarm info?).
To achieve a zero-downtime rolling update you should delegate the load-balancing to docker swarm itself:

I am trying to connect to Firestore from code running on GKE Container. Simple REST GET api is working fine, but when I access the Firestore from read/write, I am getting Missing or insufficient permissions.

Answered 2021-Jun-12 at 12:26Looks like they key itself might not be correctly visible to the pod. I would start by getting into the pod with kubectl exec --stdin --tty -- /bin/bash
and ensuring that the /var/key.json
(per your config) is accessible and has the correct credentials.
The following would be a good way to mount the secret:

i'm working on a new idea for which I've created a setup as follows on Azure Kubernetes:
- 1 cluster
- 1 node pool in said cluster
- 1 deployment which creates 2 pods in the pool
- 1 load balancer service balancing requests between the 2 pods
I'm trying to submit a json request into the loadbalancer from outside the cluster with an AKS IP, to which i encounter 502 Bad Gateway issues.
This is my deployment file

QUESTION
I am trying to have 1 redis master with 2 redis replicas tied to a 3 Quorum Sentinel on Kubernetes. I am very new to Kubernetes.
My initial plan was to have the master running on a pod tied to 1 Kubernetes SVC and the 2 replicas running on their own pods tied to another Kubernetes SVC. Finally, the 3 Sentinel pods will be tied to their own SVC. The replicas will be tied to the master SVC (because without svc, ip will change). The sentinel will also be configured and tied to master and replica SVCs. But I'm not sure if this is feasible because when master pod crashes, how will one of the replica pods move to the master SVC and become the master? Is that possible?
The second approach I had was to wrap redis pods in a replication controller and the same for sentinel as well. However, I'm not sure how to make one of the pods master and the others replicas with a replication controller.
Would any of the two approaches work? If not, is there a better design that I can adopt? Any leads would be appreciated.
...ANSWER
Answered 2021-Jun-09 at 15:49You can deploy Redis Sentinel using the Helm package manager and the Redis Helm Chart.
If you don't have Helm3
installed yet, you can use this documentation to install it.
I will provide a few explanations to illustrate how it works.
First we need to get the values.yaml
file from the Redis Helm Chart to customize our installation:

Install replica
You can use replica like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
